I have to re-upload the firmware. Would setting that fuse stop the printer from halting mid-print, or would it just stop the firmware from breaking if it gets a brown-out?

So, my Prusa Mendel, with Ramps 1.4 electronics, is in the same room as a mini fridge, on the same power circuit. I don't really have the option to move either of them, but when the fridge turns off (the compressor shuts off), the lights in the room and my computer speakers indicate that it makes a small power surge. The arduino on the printer is powered through the usb port of my laptop, which i

Update: I've ordered new filament from Protoparadigm and it's working great! I guess you get what you pay for sometimes....

Just throwing an idea out, since it doesn't happen in later layers, could it be a result of the z-home being too low?

Printing
So I've been doing a few prints with decent success, but I keep getting these little blobs, especially in the first few layers, that cause problems in subsequent layers. I'm using a .35mm j-head hot end, RAMPS 1.4, marlin firmware, and ABS

Printing
So I was printing what looked like my first successful print, after weeks of issues, and it got about an hour in and the hotend lost temperature, obviously wrecking the print. Now, if I let it cool off, it will start to heat and get up to around 215 or so, then it stops heating and cools back down. I'm not sure what's going on, any ideas?

Yeah, my Prusa is actually a makerfarm kit, and they do have absolutely awesome customer service and ship quickly, but they've been out of stock of the filament for a while, otherwise I would have just ordered from them I think

I'm using ABS. I broke it in 5 places spread out across about a meter of length, and four of the five breaks had hollow spots that were about 1 - 1.5 mm in diameter. This is what I ordered. Do you have any suggestions for places to order better filament?

I've been having a lot of trouble getting the extruder to work for any period of time since the filament will always stop pushing through and the hobbed bolt will just carve a half-circle out of the filament, and it'll go nowhere. However, when pulling the filament out (and accidentally snapping a small piece off) that it's hollow on the inside. I've got the screws with the springs on them fairly

So since the resistance looks fine, I've just bypassed the trace with a decently thick wire. I'll update if it holds or any other problems arise.

It measures at 6 Ohms. That seems somewhat low to me, but since it's made to heat the nozzle maybe it should be that low?

Ok, so I tried switching to the second extruder connection, and it blew that trace as well, again after the regulator. I'm rather confused here....

Here's an image of it. I can't find any short anywhere, and like I said it was working fine until this happened. Since I'm only using one extruder, I'm thinking I should just switch it over to E1 for a quick fix?

So, I've done one successful print on my Prusa using RAMPS 1.4 so far. However, when I was going to do a second print, the PSU (an ATX PSU) shut off and turned on a while later. I figured that it was a thermal shutoff and decided to get a more powerful psu to hopefully handle the printer without working too hard (and overheating). So I connected a 600W psu with plenty of amperage on the 12v line

Found it! There is a bad solder joint between the Mega's board and the Atmega 2560 chip. This may be hard to solder......

The voltage isn't changing, and there's continuity all the way from pin 48 on the Mega's board to the dir pin on the driver board. Is there anything at all that could cause this that anyone knows of in the firmware, or should I consider that the arduino may have a hardware problem somewhere?

So I'm running ramps 1.4 with Marlin firmware, and I'm getting a strange issue. Whenever I move my Z axis, it only moves a single direction (up). It moves the same direction regardless of whether I sent an up or down command. It's not an endstop issue, and I'm fairly certain it's not a hardware problem (though I could be wrong). It definitely not a driver since swapping those around makes no diff
